I am not a mechanic and the son in law wants wrenches for Christmas. He needs to work on the headers of a 1997 Chevy truck with a 5.7 350 engine. its a 1500 with extended cab. The truck is lifted and who knows what other mods are in place? He said it needs to be thin to get the bleeping thing in place. Would a set of S shaped or half moon wrenches work. I assume standard measurement, but..... 
Any advice is appreciated.
Thanks
